14 Claims. This invention relates to apparatus for delivering sheets from a processing machine where the sheets are operated upon individually, delivering them to desired points, and there stacking them neatly in piles. The apparatus has been devised for use with (and will herein be described in connection with) a printing press of theilat bed and cylinder type, although it may be applied equally as well to the delivery and piling of sheets discharged by any other type of processing ma-v chine.

In the delivery of sheets from a processing machine such as a printing press or the like, it is usually necessary to stop the machine for the removal of a pile of previously delivered sheets.-

This reduces the production obtainable from the machine. It is sometimes undesirable, furthermore, to deliver printed sheets from a press, one on top of the other, at frequencies which are easily attainable with modern presses, because of the danger of offsetting wet ink from one sheet onto the back of the next succeeding sheet.

We have invented a novel apparatus for delivering and piling sheets which overcomes the aforementioned objections and is characterized by numerous additional novel features and advantages which will become apparent as the following detailed description proceeds and will be particularly pointed out in the appended claims.

In a preferred embodiment of the invention, we provide a plurality of pile-supporting mechanisms with conveyor means whereby sheets delivered successively from a processing machine may be discharged onto a selected pile under the control of the operator. By means of the invention, it is possible to build up the piles in any desired order by delivering successive sheets to one or the other or by distributing the sheets among the several piles without stopping the delivery of successive sheets or otherwise interrupting the continuous flow thereof. We also provide means for automatically terminating the delivery of sheets to a given pile when it has reacted a predetermined .height. A preferred form of the invention with'certain modifications is illustrated in the accompanying drawings to which reference is made for a complete understanding. In the drawings:

Figure l is a side elevation largely diagrammatic showing the general arrangement of the apparatus of our invention in relation to a sheetprocessing machine such as a press:

Referring now in detail to the drawings and for the present to Figure 1, pile-supporting mechanisms indicated generally at In and II- are positioned to receive sheets successively from a processing machine such as a flat bed and cylinder press indicated generally 'at' I 2. The pilesupporting mechanisms comprise supporting standards "it and I3b, side frames I la and Ilb, and bracing legs I5. A tiltable sheet conveyor I6 is pivoted to each pile-supporting, mechanism as at I! and is adapted to be raised, as indicated in dotted lines in Figure 1. The conveyor I6 of 'the pile-supporting mechanism nearest the press The mechanisms Ill and II are substantially similar though not identical. The supports l3t of the mechanism III, for example, are swingably mounted on the side frames 26 of the press l2 (although they may, alternatively, be fixed thereto), while the standards I3b of the mechanism H are adapted to rest on the floor. As shown in Figures 2b and 4a., the far side frame of the press has hinge bearings 2| thereon, on which a cross girt 22 is swingably mounted on a hinge pin 23 fixed in the bearings 2|. The side frames [4a of the mechanism Ill are secured by bolts 24 to fiat faces projecting laterally from the girt 22 in planes parallel to those of the side frames 20. The side frames l4a'are connected at their rear end by a tie bar 25.

The conveyor 16 of the mechanism [0 comprises side arms 26 and 21, pivoted on hinge pins 28 extending through sleeve bearings 29 formed integral with the side frames I4a. Counter-balance springs 30 reduce the manual effort necessary to tilt the side arms on the pins 28. The ends of the arms nearest the press have locking levers 3| adapted to engage abutments 32 on the side frames of the press (see Figures 1 and 4); The side arms 26 and 21 are connected by tie rods 33 and 34 at their ends nearest to and farthest from the cylinder l6, respectively, Strippers 33a are mounted on the rod 33 and cooperate with the press cylinder to strip a sheet therefrom when released by the usual cylinder grippers.

' Ears 35 extending inwardly from the side arms provide bearings for supporting a shaft 36. Conveyor belts or tapes 31 are trained around the shaft 36, and pulleys 38 carried on brackets 39 mounted on the rod 34. The tape 31 are also trained about a driving shaft 40 and a tightener shaft 4|, the latter being carried on brackets 42 swingable on a cross shaft 43. The drive shaft 40 is coaxial with the pins 26 and is rotatably supported in bearings carried by the latter. The shaft 40 extends through the pin 28 on the far side and is provided with a bevel pinion 44, meshing with a similar pinion 45 (see Figures 2b and 4a). The pinion 45 is secured to a shaft 401: journaled vertically in the upper end of the hinge pin 23, as illustrated in Figure 4a. The shaft 40a is driven through a similar bevel pinion drive 44a, 44b from a pulley 46 mounted on a shaft 46a journaled in a bracket 46b secured to the pin 23. The pulley 46 is driven by a motor 41 through a chain and sprocket 48 and a belt and pulley drive 49.

The pile support ll! of the mechanism I0 is suspended on cables 56 trained over pulleys 5| and wound on drums secured to a shaft 52. The pulleys 5| are journaled on stub shafts 53. Automatic lowering means for the support l9 include a ratchet wheel 54 and an'oscillating crank 55 having a pawl 56 cooperating therewith. The details of this mechanism are illustrated in the copending application of Joseph Sinkovitz, Serial No. 144,607, but any convenient automatic lowering means may be employed. The crank *55 is oscillated by a reciprocating link 56, a bell crank 51 pivoted on the near standard He, and a link 58. The link 56 is actuated by cam or other means in timed relation to the operation of the press cylinder I6 (Fig. 1).

Side joggers 59 and a rear jogger 60 causes the sheets discharged onto the support [9 from the conveyor tapes to be piled neatly in a perpendicular pile. The side joggers are secured by brackets 59a to cross shafts 6| slidable in the side fram 1 4a. Each of the shafts 6| is composed of two parts connected by a spring-pressed telescoping joint (not shown). The rear Jogger 60 is carried on a cross shaft 62, the ends of which are journaled in blocks 63 adjustably secured to links 64. The links 64 are reciprocated axially by cranks 65, secured to a cross shaft 66. Theshaft 66 is oscillated by a crank 61 and a link 610. connected to the short arm of bell crank 51. The ends of the links 64 remote from the cranks 61 are pivoted to cranks 68 carried on vertical shafts 69. The shafts 69 are journaled in the tie bar 25 and are provided with cranks I6 pivoted to the shafts 6|. Reciprocation of the link 64 causes the jogger 59 and 60 to move toward and away from the pile, thus maintainmg each sheet as deposited in accurately superposed position relative to the sheets previously delivered. Bendable guide fingers II are secured to the tie bar 25. They normally extend forwardly therefrom to a point above the pulleys 36 when the conveyor of the adjacent supporting mechanism is raised. The function of the fingers H is to guide the sheets discharged from the conveyor tapes downwardly onto th pile carried on the support IS. The fingers of the mechanism III are pressed downwardly into the lower of their alternate positions illustrated, by the conveyor l6 of the mechanism ll except when the latter is tilted up.

The pile-supporting mechanism l I is similar in general to that already described in detail and corresponding parts thereof are designated by the same reference numerals. Numerous features of difference will be specifically referred to. The standards l3b are in the form of flat plates to which the depending portions of the side frames Mb. are bolted. The hold-down latching levers 3! of the mechanism II cooperate with abutments 12 secured to the side frames I4a, as shown in Figs. 1 and 3b. This is the only mechanical connection between the mechanisms l6 and II so the latter may easily be removed for replacement or transfer to another machine. When the conveyor frame I6 of the mechanism H is in the position illustrated in Figures 3a and 3b, it forms, in effect, a continuation of the con veyor of the mechanism Ill. The conveyor tapes of the mechanism II are driven by a motor 41a through a belt and pulley drive 49a. The motor 41a is controlled by a switch 13 mounted on the far side frame l4b. A projection 14 on the side arm 21 causes the switch to be closed when the conveyor frame is lowered to its illustrated position. When the frame is raised by releasing the levers 3| the switch 13 is opened and the motor 41a stops.

The crank 55 of the mechanism II is actuated by a link 15 having one end pivoted thereto. The other end of the link has a pin and slot connection to the crank 55 of the mechanism H). A bell crank 51a is actuated by the link 58 and. in turn, operates link 68 which moves the joggers. The link 15 reciprocates through a stirrup 16 secured to the side arm 26. When the conveyor N5 of the mechanism H is uplifted the stirrup simply lifts the end of the link I5 off the pin in the crank 55. A latch bar ll, pivoted on the near side frame I4b, has a notch adapted to engage the projecting end of shaft 43a to hold the conveyor l6 in elevated position, as shown in Figure 1. Press throw-off levers 18 are pivoted on the inner side frames Ma and l4b and are connected by link 19 having a universal joint therein. The lever 18 on the side frame Ha is connected by suitable means (not shown) side frames of the pile-supporting mechanism nearest the press and the pile support carried thereby may be swung laterally without moving the associated conveyor frame. This is in contrast with the structure of Figures- 1 to 3a, wherein the conveyor of the mechanism must be uplifted before the latter can be swung about the vertical pin 23 and the conveyor swings with the rest of the mechanism. The principal difference between the structure of Figures'5 to 7 and that already described in detail is that, in the former, the pins on which the conveyor frame is pivoted are not carried on the side frames of the pile-supporting mechanism. As clearly shown in Figures 5 through 7, bearing brackets 88 are carried on the side frames 28 of the press l2. Pins28a are secured inbearing sleeves 84, formed on the brackets 88 and provide pivotal bearings for the side arms 28 and 21 of the conveyor frame. The bracket 83 on the far side overlies the girt 22 as shown in Figure '7. Screws 83a and 83b extend through the foot of said bracket and are threaded respectively into the side frame and the girt. Screws 88c and 88d extend through the near bracket, and are threaded respectively into the girt and side anism nearest the press-may be removed while the conveyor associated with said mechanism remains effective to deliver sheets to a succeeding supporting mechanism. Removal may be facilitated by swinging the pile support out from under the conveyor frame but is.possible without doing so. The conveyor may also be caused to swing with the rest of the mechanism by replacing screws 88b and 830. and removing screws 83a and 83d.

It will be apparent that when the screws 88a and 88d are in place, the bearing brackets 83 and 84 supporting the conveyor side arms 28 and 21 are secured to the side frames 28. When the screws 83b and 830 are in place, however, the bearing brackets 83 and 84 are secured to the cross girt 22.

Figure 8 illustrates a modification wherein the conveyor frame of the second pile-supporting mechanism is raised and lowered continuously in timed relation to the operation of the press, I

may be increased, as desired, above the two illustrated in the drawings and may be arranged otherwise than in tandem, if desired. As in the case of the modification of Figures 5 through 7, that shown in Figure 815 similar, in general, to the apparatus shown in Figures 1 through 4. The following description, therefore, will be confined to the features which distinguish the particular modification shown in Figure 8 from the other forms of the invention.

Figure 8 shows in side elevation a pile support 88, arranged adjacent a press 81 and having a conveyor 88 extending through the latter.

' second pile support (not shown), similar to 88 except that it is supported in about the same manner as the mechanism of Figure 1, has a conveyor 88 extending over the supporting mechanism 88. The conveyor 88 is adapted to deliver sheets received from the press cylinder either to the pile support 80 of the mechanism 88, or to the conveyor 88. The conveyor 88 is adapted to be raised and lowered automatically between the delivery of successive sheets from the press. For this purpose, the latching levers 8| are held out of operative position (i. e., in the dotted line position) by pivoted fingers 88a. A link 8| has a fork formed at its upper end for engagement ,with a pin 82extending laterally from the near side arm of the conveyor 88. The link 8| is pivoted to a lever 88, mounted on the near side frame 84 of the press 81 for angular movement thereon. The lever 88 is oscillated by means of ,a link 85 and a crank 88 carried on a shaft 81.

The shaft 81 is journaled in the near side frame 84 and is driven in timed relation to the operation of the press by a chain and sprocket drive 88. Oscillation of the lever 88 causes reciprocation of the link 8|. This causes the conveyor to tilt up and down, pivoting on its pins 28 (not shown). When the conveyor 88 is raised, the conveyor 88 delivers a sheet to the pile support 88. When the conveyor 88 is lowered it receives a sheet discharged by the conveyor 88 and delivers it to the pile support of the mechanism with which the conveyor 88 is associated. It is thus possible to deliver alternate sheets to different piles.

The jogger-operating mechanism shown in Figure 8 differs slightly from that of Figures 1 through 4. The bell crank 51 is actuated in the same manner and causes reciprocation of a link 81!) corresponding to the link 81a. The link 81b through a crank 81', oscillates a shaft 88 and cranks 85a. carried thereby. These cranks operate the jogger mechanism in the same manner as the cranks 85 of Figure 3b.

A lever 88 is pivoted on the side frame 84 at I80. Its lower end has a pivotal connection with the link 58. Its upper end has a pin cooperating with the slotted end oflink 15. The press throw-off lever 18a of Figure 8 differs slightly inarrangement from lever 18 of Figures 3a and 3b but corresponds thereto in operation and function.

Figures 9 through illustrate a further modification including means for automatically caus- 1 ing the sheets being delivered to be diverted from the first pile-supporting mechanism to the see- 0nd when the pile on the former has reached a predetermined height.-

As shown in the drawings, a pile-supporting mechanism |88a is disposed adjacent a press, the side frames of which are shown at H, and is provided with a conveyor I82. The second pile-supporting mechanism (not shown) has a conveyor I08. The latter is shown in elevated position in Figure 9, so that sheets discharged by the conveyor I02 build up in a pile on a support I04, suspended from the mechanism I000.

, The conveyor I03, however, is adapted to be automatically lowered by means to be described shortly, whereupon the latching levers 3! become effective to hold the conveyor in its lowermost position.

The conveyor I03 is normally held in elevated position by a finger I05 extending radially of a shaft I06. The finger I05 bears against a boss I01 on the near side arm of the conveyor I03. The shaft I06 is journaled in the near side frame of the mechanism Ia. The finger I is normally held erect by cooperating detents I00 and I09. The former is carried on the shaft I06. The latter forms part of a bell crank IIO pivoted on the near side frame of the mechanism I00a at III. A link H2 is pivoted to the bell crank H0 and extends downwardly through the support I04 and a guide bearing H3 extending from the near press frame IN. A set collar H4 is adjustable along the link II2. As a result, when the support I04 has been lowered sufficiently to engage the collar H4, the link H2 is pulled down on further lowering of the support. The support is automatically lowered by oscillating crank 55 and the ratchet and pawl mechanism operated thereby, as in vthe form of the invention first described.

As the link H2 is pulled down, the detent I09 disengages the detent I08. The shaft I06 is normally urged in counter-clockwise direction by a suitable coil spring (not shown) so that when the detent I09 disengages the detent I08 the finger I05 swings to theposition shown in IFigure 10, thus permitting downward movement v of the conveyor I03.

Means for positively tilting the conveyor to its y lowermost position include a link I I5 which normally bears against a roller H6 mounted on a crank II'I extending from the shaft I06. The

link 5 has a notch H0 adjacent its upper end v adapted to cooperate with a pin H9, extending Figure 9 the link 5 merely reciprocates idly as the position shown in Figure l, whereupon the latching levers 3| become effective to lock the conveyor in that position.

From the foregoing detailed description it will be seen that the invention provides means for expeditiously handling sheets discharged successively by a processing machine of any kind, a typical example of which is a flat bed and cylinder press. Perhaps the principal' advantage of the invention is that it permits the removal of a pole of sheets which has accumulated on one supporting mechanism without necessitating the stoppage of the flow of sheets. A pile of sheets delivered to the mechanism I0 of Figures 1 through 4 may be removed after lowering the conveyor I6 to the position shown in solid lines in Figure 1, so that sheets delivered from the press while the pile of the mechanism I0 is being removed are delivered to the support I9 of the mechanism II. This operation may be facilitated (in the form of the invention shown in Figures 5-7) by swinging the mechanism on its hinge pin 2| without moving the associated conveyor I6. A substantial increase in the production obtainable from a press or other processing machine can thus be achieved, since the time for unloading piles amounts to from 5 to 10% of the total running time. As before stated, the number of pile supporting mechanisms may be increased beyond the two illustrated and described herein. The invention also permits sheets to be delivered alternately to one pile and then to another and also the automatic shifting of the delivery from one pile to another when the former has built up to a predetermined height.

The conveyors of the pile-supporting mechanisms are driven by separate motors. In case of a shut-down of the press in an emergency or the like the last sheet discharged from the press is not stopped in its path, but is carried to the pile by the continued operation of the conveyor-driving motors. The switch automatically controlling the motor driving the oonveyor of the second pile-supporting mechanism causes the conveyor to be driven only when it is actually in position to receive the sheets. The conveyor of the second mechanism, furthermore, may be shifted from inoperative position to operative position without stopping the delivery of sheets, since the .movement may be accomplished between the delivery of the successive sheets. Similarly, the delivery of sheets to the second supporting mechanism may be arrested simply by lifting its conveyor. This permits easy inspection of the following sheets which are delivered to the first supporting mechanism. On releasing the latching levers 3|, the mechanism nearest the press can be swung away from the latter to give access to the inking mechanism or the bed of the press (not shown). Since the conveyor drive includes bevel gearing coaxial with the hinge pin, it remains operative at all times. Swinging of the mechanism merely causes bevel gears 45 and 44b to rotate as gears 44 and 44a traverse orbital paths about the shaft 40a.

Although we have illustrated herein only a preferred embodiment of the invention and a few modifications, it will be understood that changes in the construction and operation disclosed may be made without departing from the spirit of the invention or the scope of the appended claims.
